Minimum Cricket Matches for Fair Win Chance

Fair chance means probability of winning at least one match $\ge 1/2$. $P(\text{winning at least 1}) = 1 - (5/6)^n \ge 1/2 \implies (5/6)^n \le 1/2$. For $n = 3$: $(5/6)^3 = 125/216 \approx 0.578 > 0.5$. For $n = 4$: $(5/6)^4 = 625/1296 \approx 0.482 \le 0.5$. Minimum matches required = 4.
